–l :: If you want Yasuo to perform a port scan, use this switch to provide an input file with new-line separated IP addresses, similar to nmap’s -iL option
-s :: Provide custom signature file. [./yasuo.rb -s mysignatures.yaml -f nmap.xml] [Default – signatures.yaml]
–f :: If you do not want Yasuo to perform a port scan and already have an nmap output in XML format, use this switch to feed the nmap output
–u :: Takes a newline-separated file of URLs saved from the previous run of Yasuo.
–n :: Tells Yasuo to not ping the host while performing the port scan. Standard nmap option.
–p :: Use this switch to provide port number(s)/range
–A :: Use this switch to scan all the 65535 ports. Standard nmap option.
-b [all/form/basic] :: If the discovered application implements authentication, use this switch to brute-force the auth. “all” will brute-force both form & HTTP basic auth. “form” will only brute-force form-based auth. “basic” will only brute-force HTTP basic auth.
–t :: Specify the maximum number of threads
